This paper considers an extension of classical distribution problems and introduces the time-dependent fleet size and mix multi-depot vehicle routing problem. This important class of problems finds applications in urban logistics and service design. The solution to this problem impacts …
One of the standard approaches for solving discrete optimization problems which include the aspect of time, such as the traveling salesman problem with time windows or the shortest path problem with time windows is to derive a so-called time-indexed formulation. …
© 2013 IEEE.Fleet management plays a central role in several application contexts such as distribution planning, mail delivery, garbage collection, salt gritting, field service routing. Since road congestion has a big impact on driving times, fleet management can be enhanced …
Hazardous material transportation is an integral part of industries that pose significant risks. Hazardous material transportation risk of is proportional to the volume of materials transferred, the length of the link, and the population density, which varies over time. By …
This paper studies a time-dependent green vehicle routing problem (TDGVRP) with the consideration of traffic congestion. In this work, the objective is to design the vehicle scheduling plan, with the goal of reducing carbon emissions, which has a positive linear …
Many companies that conduct a perishable product delivery face a practical problem when an increasingly congested road setting exists. An inappropriate routing scheme not only leads to higher delivery costs but also results in customers’ dissatisfaction. The previous literature paid …
Logistics enterprises are moving towards high efficiency and green. As an emerging technology, unmanned aerial vehicle (UAV, also known as drone) is very useful to cope with flexible and fast delivery. Electric vehicles (EVs), as new energy vehicles, are the …
Urban on-demand transportation services are booming in both passenger transportation and the transportation of goods. The types of service differ in timeliness and compensation and, until now, providers operate larger fleets separately for each type of service. While this may …
© 2022 The Author(s)We study an operational planning problem arising in the offshore oil and gas industry, in which we determine routes, as well as sailing speeds along these routes, for a set of platform supply vessels (PSVs) servicing a …
Recently Green Location-Routing Problem (GLRP) has been considered by many researchers. The GLRP includes location for depots and routing the vehicles simultaneously by considering environmental aspects. In this work an extension of GLRP in the presence of traffic congestion and …
